here is a quick photo of a opamp circuit I'm trying to get working in order to filter ir diode signal. What is wrong with the circuit? I'm using a basic stamp 2 to measure the input. Sorry for the poor photo I have to do this from my phone. This is supposed to be a high pass filter circuit
This would go much better if the image was uploaded to this site. Also if you could post an actual schematic. You don't mention what the op-amp actually is.
